Golly it's fatiguing in those jobs, but you actually sweat, as cold as it is, when you're firing. Not so much the physical labor (you forget about that) as it is the mental straight. Figuring out the deflection to allow for the target (moving target + stationary target call for different deflections) watching your gun for the dozens of malfunctions that might occur. You really learn to respect + care for your gun - it's your round trip ticket.

I don't know if I'll get to fly anymore up here as I've completed my 6 missions, that's all you're supposed to have. 3 more days here then for the final week at Vegas. Hope I don't flunk anything, We've got a lot of tests from now till we graduate. Got 95% today in Harmonization that is associated with sighting. Would take some time to explain that, so will let that go. I don't know by far, all there is to know about that.
